Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8 - 9. Dark longitudinal lines on body; caudal fin black with light margin dorsally; pectoral base with 1-2 black spots (Ref. 5493).

Biology     Glossary (e.g. epibenthic)

Inhabits brackish mangrove estuaries and lower reaches of freshwater streams, usually on mud bottoms (Ref. 44894). Usually found in lagoons and estuaries, particularly where there is vegetation (Ref. 6028, 79840). Occurs frequently in mangrove swamps (Ref. 2847, 79840). Occasionally ascends rivers (Ref. 6028). Feeds mainly on small fishes and crustaceans (Ref. 6028, 79840). Marketed fresh (Ref. 12693).

Estimates based on models

Preferred temperature (Ref. 115969): 24.7 - 29.1, mean 28.2 (based on 1196 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00575 (0.00231 - 0.01432), b=3.07 (2.85 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.66 se; based on food items.
